Model-driven development of personalized, multichannel interfaces for audiovisual search: the PHAROS approach

In this paper we illustrate the model-driven development approach applied to the user interface of an audiovisual search application, within the European project PHAROS. We show how conceptual modelling can capture the most complex features of an audio-visual Web search portal, which allows users to pose advanced queries over multimedia materials, access results of queries using multimodal and multi-channel interfaces, and customize the search experience by saving queries of interest in a personal profile, so that they can be exploited for asynchronous notification of new relevant audiovisual information. We show how model-driven development can help the generation of the code for sophisticated Rich Internet Application front-ends, typical of the multimedia portals of the future.
